Performance measurement job control for 5G networks and network slicing

ABSTRACT

Systems and methods of performance management over a life cycle is provided. A measurement job control service producer receives, from an authorized consumer, a request to consume a measurement job control service. The request is analyzed, appropriate action is taken to satisfy the request and a response indicating the request result is generated. A request is to create or terminate a measurement job to collect the performance data for a NF, NSSI, NSI, or network. To create a job, the producer checks if the job can be supported by an existing job, creates the job if no such existing job exists, and otherwise responds that the job can be supported by the existing job. To terminate a job, the producer checks if the job is serving other consumers, terminates the job if other consumers are not being served, and otherwise responds that the job is currently serving other consumers.

PRIORITY CLAIM

This application claims the benefit of priority under 35 U.S.C. 119(e) to U.S. Provisional Patent Application Ser. No. 62/634,000, filed Feb. 22, 2018, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

Embodiments pertain to radio access networks (RANs). Some embodiments relate to cellular and wireless local area network (WLAN) networks, including Third Generation Partnership Project Long Term Evolution (3GPP LTE) networks and LTE advanced (LTE-A) networks as well as legacy networks, 4^(th) generation (4G) networks and 5^(th) generation (5G) networks. Some embodiments relate to management of performance measurement jobs.

BACKGROUND

The use of 3GPP LTE systems (including LTE and LTE-Advanced systems) has increased due to both an increase in the types of devices user equipment (UEs) using network resources as well as the amount of data and bandwidth being used by various applications, such as video streaming, operating on these UEs. With the vast increase in number and diversity of communication devices, the corresponding network environment, including routers, switches, bridges, gateways, firewalls, and load balancers, has become increasingly complicated, especially with the advent of next generation (NG) systems.

To add further complexity to the variety of services provided by the network devices, many physical implementations of the network devices are propriety and may be unable to incorporate new or adjusted physical components to compensate for different network conditions. This has led to the development of Network Function Virtualization (NFV), which may provide a virtualized environment able to provide any network function or service able to be delivered on general purpose computing systems in a data center as software applications called Virtual Network Functions (VNFs). The use of NFV may provide flexibility in configuring network elements, enabling dynamic network optimization and quicker adaptation of new technologies. As 5G systems develop, flexibility in determining performance management of such systems, including lifecycle of performance measurement jobs also is to be developed.

DETAILED DESCRIPTION

The following description and the drawings sufficiently illustrate specific embodiments to enable those skilled in the art to practice them. Other embodiments may incorporate structural, logical, electrical, process, and other changes. Portions and features of some embodiments may be included in, or substituted for, those of other embodiments. Embodiments set forth in the claims encompass all available equivalents of those claims.

FIG. 1 illustrates a combined communication system in accordance with some embodiments. The system 100 includes 3GPP LTE/4G and NG network functions. A network function can be implemented as a discrete network element on a dedicated hardware, as a software instance running on dedicated hardware, or as a virtualized function instantiated on an appropriate platform, e.g., dedicated hardware or a cloud infrastructure.

The evolved packet core (EPC) of the LTE/4G network contains protocol and reference points defined for each entity. These core network (CN) entities may include a mobility management entity (MME) 122, serving gateway (S-GW) 124, and paging gateway (P-GW) 126.

In the NG network, the control plane and the user plane may be separated, which may permit independent scaling and distribution of the resources of each plane. The UE 102 may be connected to either an access network or random access network (RAN) 110 and/or may be connected to the NG-RAN 130 (gNB) or an Access and Mobility Function (AMF) 142. The RAN may be an eNB, a gNB or a general non-3GPP access point, such as that for Wi-Fi. The NG core network may contain multiple network functions besides the AMF 112. The network functions may include a User Plane Function (UPF) 146, a Session Management Function (SMF) 144, a Policy Control Function (PCF) 132, an Application Function (AF) 148, an Authentication Server Function (AUSF) 152 and User Data Management (UDM) 128. The various elements are connected by the NG reference points shown in FIG. 1.

The AMF 142 may provide UE-based authentication, authorization, mobility management, etc. The AMF 142 may be independent of the access technologies. The SMF 144 may be responsible for session management and allocation of IP addresses to the UE 102. The SMF 144 may also select and control the UPF 146 for data transfer. The SMF 144 may be associated with a single session of the UE 102 or multiple sessions of the UE 102. This is to say that the UE 102 may have multiple 5G sessions. Different SMFs may be allocated to each session. The use of different SMFs may permit each session to be individually managed. As a consequence, the functionalities of each session may be independent of each other. The UPF 126 may be connected with a data network, with which the UE 102 may communicate, the UE 102 transmitting uplink data to or receiving downlink data from the data network.

The AF 148 may provide information on the packet flow to the PCF 132 responsible for policy control to support a desired QoS. The PCF 132 may set mobility and session management policies for the UE 102. To this end, the PCF 132 may use the packet flow information to determine the appropriate policies for proper operation of the AMF 142 and SMF 144. The AUSF 152 may store data for UE authentication. The UDM 128 may similarly store the UE subscription data.

The gNB 130 may be a standalone gNB or a non-standalone gNB, e.g., operating in Dual Connectivity (DC) mode as a booster controlled by the eNB 110 through an X2 or Xn interface. At least some of functionality of the EPC and the NG CN may be shared (alternatively, separate components may be used for each of the combined component shown). The eNB 110 may be connected with an MME 122 of the EPC through an S1 interface and with a SGW 124 of the EPC 120 through an S1-U interface. The MME 122 may be connected with an HSS 128 through an S6a interface while the UDM is connected to the AMF 142 through the N8 interface. The SGW 124 may connected with the PGW 126 through an S5 interface (control plane PGW-C through S5-C and user plane PGW-U through S5-U). The PGW 126 may serve as an IP anchor for data through the internet.

The NG CN, as above, may contain an AMF 142, SMF 144 and UPF 146, among others. The eNB 110 and gNB 130 may communicate data with the SGW 124 of the EPC 120 and the UPF 146 of the NG CN. The MME 122 and the AMF 142 may be connected via the N26 interface to provide control information there between, if the N26 interface is supported by the EPC 120. In some embodiments, when the gNB 130 is a standalone gNB, the 5G CN and the EPC 120 may be connected via the N26 interface.

FIG. 2 illustrates a block diagram of a communication device in accordance with some embodiments. The communication device 200 may be a UE such as a specialized computer, a personal or laptop computer (PC), a tablet PC, or a smart phone, dedicated network equipment such as an eNB, a server running software to configure the server to operate as a network device, or any machine capable of executing instructions (sequential or otherwise) that specify actions to be taken by that machine. For example, the communication device 200 may be implemented as one or more of the devices shown in FIG. 1.

Examples, as described herein, may include, or may operate on, logic or a number of components, modules, or mechanisms. Modules and components are tangible entities (e.g., hardware) capable of performing specified operations and may be configured or arranged in a certain manner. In an example, circuits may be arranged (e.g., internally or with respect to external entities such as other circuits) in a specified manner as a module. In an example, the whole or part of one or more computer systems (e.g., a standalone, client or server computer system) or one or more hardware processors may be configured by firmware or software (e.g., instructions, an application portion, or an application) as a module that operates to perform specified operations. In an example, the software may reside on a machine readable medium. In an example, the software, when executed by the underlying hardware of the module, causes the hardware to perform the specified operations.

Accordingly, the term “module” (and “component”) is understood to encompass a tangible entity, be that an entity that is physically constructed, specifically configured (e.g., hardwired), or temporarily (e.g., transitorily) configured (e.g., programmed) to operate in a specified manner or to perform part or all of any operation described herein. Considering examples in which modules are temporarily configured, each of the modules need not be instantiated at any one moment in time. For example, where the modules comprise a general-purpose hardware processor configured using software, the general-purpose hardware processor may be configured as respective different modules at different times. Software may accordingly configure a hardware processor, for example, to constitute a particular module at one instance of time and to constitute a different module at a different instance of time.

The communication device 200 may include a hardware processor 202 (e.g., a central processing unit (CPU), a GPU, a hardware processor core, or any combination thereof), a main memory 204 and a static memory 206, some or all of which may communicate with each other via an interlink (e.g., bus) 208. The main memory 204 may contain any or all of removable storage and non-removable storage, volatile memory or non-volatile memory. The communication device 200 may further include a display unit 210 such as a video display, an alphanumeric input device 212 (e.g., a keyboard), and a user interface (UI) navigation device 214 (e.g., a mouse). In an example, the display unit 210, input device 212 and UI navigation device 214 may be a touch screen display. The communication device 200 may additionally include a storage device (e.g., drive unit) 216, a signal generation device 218 (e.g., a speaker), a network interface device 220, and one or more sensors, such as a global positioning system (GPS) sensor, compass, accelerometer, or other sensor. The communication device 200 may further include an output controller, such as a serial (e.g., universal serial bus (USB), parallel, or other wired or wireless (e.g., infrared (IR), near field communication (NFC), etc.) connection to communicate or control one or more peripheral devices (e.g., a printer, card reader, etc.).

The storage device 216 may include a non-transitory machine readable medium 222 (hereinafter simply referred to as machine readable medium) on which is stored one or more sets of data structures or instructions 224 (e.g., software) embodying or utilized by any one or more of the techniques or functions described herein. The instructions 224 may also reside, completely or at least partially, within the main memory 204, within static memory 206, and/or within the hardware processor 202 during execution thereof by the communication device 200. While the machine readable medium 222 is illustrated as a single medium, the term “machine readable medium” may include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) configured to store the one or more instructions 224.

The term “machine readable medium” may include any medium that is capable of storing, encoding, or carrying instructions for execution by the communication device 200 and that cause the communication device 200 to perform any one or more of the techniques of the present disclosure, or that is capable of storing, encoding or carrying data structures used by or associated with such instructions. Non-limiting machine readable medium examples may include solid-state memories, and optical and magnetic media. Specific examples of machine readable media may include: non-volatile memory, such as semiconductor memory devices (e.g., Electrically Programmable Read-Only Memory (EPROM), Electrically Erasable Programmable Read-Only Memory (EEPROM)) and flash memory devices; magnetic disks, such as internal hard disks and removable disks; magneto-optical disks; Random Access Memory (RAM); and CD-ROM and DVD-ROM disks.

The instructions 224 may further be transmitted or received over a communications network using a transmission medium 226 via the network interface device 220 utilizing any one of a number of transfer protocols (e.g., frame relay, internet protocol (IP), transmission control protocol (TCP), user datagram protocol (UDP), hypertext transfer protocol (HTTP), etc.). Example communication networks may include a local area network (LAN), a wide area network (WAN), a packet data network (e.g., the Internet), mobile telephone networks (e.g., cellular networks), Plain Old Telephone (POTS) networks, and wireless data networks. Communications over the networks may include one or more different protocols, such as Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards known as Wi-Fi, IEEE 802.16 family of standards known as WiMax, IEEE 802.15.4 family of standards, a Long Term Evolution (LTE) family of standards, a Universal Mobile Telecommunications System (UMTS) family of standards, peer-to-peer (P2P) networks, a next generation (NG)/5^(th) generation (5G) standards among others. In an example, the network interface device 220 may include one or more physical jacks (e.g., Ethernet, coaxial, or phone jacks) or one or more antennas to connect to the transmission medium 226.

FIG. 3 illustrates an NFV network management architecture in accordance with some embodiments. As illustrated, the NFV network management architecture 300 may include a number of elements (each of which may contain physical and/or virtualized components), including a Network Function Virtualization Infrastructure (NFVI) 310, Network elements (NEs) 390, Virtual Network Functions (VNFs) 320, a Domain Manager (DM) 330, an Element Manager (EM) 332, a Network Manager (NM) 342, and an NFV Management and Orchestration (NFV-MANO) 380. The NFV-MANO 380, which may be replaced as indicated herein by multiple NFV-MANOs, may comprise a Virtualized Infrastructure Manager (VIM) 370, a VNF Manager (VNFM) 350, and a Network Function Virtualization Orchestrator (NFVO) 360. The NM 342 may be contained in an Operations Support System/Business Support System (OSS/BSS) 320, with the DM 330 and NM 342 forming the 3GPP management system 334.

The NFV network management architecture 300 may be implemented by, for example, a data center comprising one or more servers in the cloud. The NFV network management architecture 300, in some embodiments, may include one or more physical devices and/or one or more applications hosted on a distributed computing platform, a cloud computing platform, a centralized hardware system, a server, a computing device, and/or an external network-to-network interface device, among others. In some cases, the virtualized resource performance measurement may include, for example, latency, jitter, bandwidth, packet loss, nodal connectivity, compute, network, and/or storage resources, accounting, fault and/or security measurements. In particular, the NEs 390 may comprise physical network functions (PNF) including both hardware such as processors, antennas, amplifiers, transmit and receive chains, as well as software. The VNFs 320 may be instantiated in one or more servers. Each of the VNFs 320, DM 330 and the NEs 390 may contain an EM 322, 332, 392.

The NFV Management and Orchestration (NFV-MANO) 380 may manage the NFVI 310. The NFV-MANO 380 may orchestrate the instantiation of network services, and the allocation of resources used by the VNFs 320. The NFV-MANO 380 may, along with the OSS/BSS 340, be used by external entities to deliver various NFV business benefits. The OSS/BSS 340 may include the collection of systems and management applications that a service provider may use to operate their business: management of customers, ordering, products and revenues—for example, payment or account transactions, as well as telecommunications network components and supporting processes including network component configuration, network service provisioning and fault handling. The NFV-MANO 380 may create or terminate a VNF 320, increase or decrease the VNF capacity, or update or upgrade software and/or configuration of a VNF. The NFV-MANO 380 may include a Virtualized Infrastructure Manager (VIM) 370, a VNF Manager (VNFM) 350 and a NFV Orchestrator (NFVO) 360. The NFV-MANO 380 may have access to various data repositories including network services, VNFs available, NFV instances and NFVI resources with which to determine resource allocation.

The VIM 370 may control and manage the NFVI resources via Nf-Vi reference points within the infrastructure sub-domain. The VIM 370 may further collect and forward performance measurements and events to the VNFM 350 via Vi-VNFM and to the NFVO 360 via Or-Vi reference points. The NFVO 360 may be responsible for managing new VNFs and other network services, including lifecycle management of different network services, which may include VNF instances, global resource management, validation and authorization of NFVI resource requests and policy management for various network services. The NFVO 360 may coordinate VNFs 320 as part of network services that jointly realize a more complex function, including joint instantiation and configuration, configuring required connections between different VNFs 320, and managing dynamic changes of the configuration. The NFVO 360 may provide this orchestration through an OS-Ma-NFVO reference point with the NM 342. The VNFM 350 may orchestrate NFVI resources via the VIM 370 and provide overall coordination and adaptation for configuration and event reporting between the VNFM 350 and the EMs and NM. The former may involve discovering available services, managing virtualized resource availability/allocation/release and providing virtualized resource fault/performance management. The latter may involve lifecycle management that may include instantiating a VNF, scaling and updating the VNF instances, and terminating the network service, releasing the NFVI resources for the service to the NFVI resource pool to be used by other services.

The VNFM 350 may be responsible for the lifecycle management of the VNFs 320 via the Ve-VNFM-VNF reference point and may interface to EMs 322, 332 through the Ve-VNFM-EM reference point. The VNFM 350 may be assigned the management of a single VNF 320, or the management of multiple VNFs 320 of the same type or of different types. Thus, although only one VNFM 350 is shown in FIG. 3, different VNFMs 350 may be associated with the different VNFs 320 for performance measurement and other responsibilities. The VNFM 350 may provide a number of VNF functionalities, including instantiation (and configuration if required by the VNF deployment template), software update/upgrade, modification, scaling out/in and up/down, collection of NFVI performance measurement results and faults/events information and correlation to VNF instance-related events/faults, healing, termination, lifecycle management change notification, integrity management, and event reporting.

The VIM 370 may be responsible for controlling and managing the NFVI compute, storage and network resources, usually within one operator's Infrastructure Domain. The VIM 370 may be specialized in handling a certain type of NFVI resource (e.g. compute-only, storage-only, networking-only), or may be capable of managing multiple types of NFVI resources. The VIM 370 may, among others, orchestrate the allocation/upgrade/release/reclamation of NFVI resources (including the optimization of such resources usage) and manage the association of the virtualized resources to the physical compute, storage, networking resources, and manage repository inventory-related information of NFVI hardware resources (compute, storage, networking) and software resources (e.g. hypervisors), and discovery of the capabilities and features (e.g. related to usage optimization) of such resources.

The NFVI 310 may itself contain various virtualized and non-virtualized resources. These may include a plurality of virtual machines (VMs) that may provide computational abilities (CPU), one or more memories that may provide storage at either block or file-system level and one or more networking elements that may include networks, subnets, ports, addresses, links and forwarding rules to ensure intra- and inter-VNF connectivity.

Each VNF 320 may provide a network function that is decoupled from infrastructure resources (computational resources, networking resources, memory) used to provide the network function. Although not shown, the VNFs 320 can be chained with other VNFs 320 and/or other physical network function to realize a network service. The virtualized resources may provide the VNFs 320 with desired resources. Resource allocation in the NFVI 310 may simultaneously meet numerous requirements and constraints, such as low latency or high bandwidth links to other communication endpoints.

The VNFs 320, like the NEs 390 may be managed by one or more EMs 322, 332, 392. The EM may provide functions for management of virtual or physical network elements, depending on the instantiation. The EM may manage individual network elements and network elements of a sub-network, which may include relations between the network elements. For example, the EM 322 of a VNF 320 may be responsible for configuration for the network functions provided by a VNF 320, fault management for the network functions provided by the VNF 320, accounting for the usage of VNF functions, and collecting performance measurement results for the functions provided by the VNF 320.

The EMs 322, 332, 392 (whether in a VNF 320 or NE 390) may be managed by the NM 342 of the OSSiBSS 340 through Itf-N reference points. The NM 342 may provide functions with the responsibility for the management of a network, mainly as supported by the EM 332 but may also involve direct access to the network elements. The NM 342 may connect and disconnect VNF external interfaces to physical network function interfaces at the request of the NFVO 360.

As above, the various components of the system may be connected through different reference points. The references points between the NFV-MANO 380 and the functional blocks of the system may include an Os-Ma-NFVO between the NM 342 and NFVO 360, a Ve-VNFM-EM between the EM 322, 332 and the VNFM 350, a Ve-VNFM-VNF between a VNF 320 and the VNFM 350, a Nf-Vi between the NFVI 310 and the VIM 370, an Or-VNFM between the NFVO 360 and the VNFM 350, an Or-Vi between the NFVO 360 and the VIM 370, and a Vi-VNFM between the VIM 370 and the VNFM 350. An Or-Vi interface may implement the VNF software image management interface and interfaces for the management of virtualized resources, their catalogue, performance and failure on the Or-Vi reference point. An Or-Vnfm interface may implement a virtualized resource management interface on the Or-Vnfm reference point. A Ve-Vnfm interface may implement a virtualized resource performance/fault management on the Ve-Vnfm reference point.

As above, with the advent of 5G networks and disparate devices (such as Machine Type Communication (MTC), enhanced Mobile Broadband (eMBB) and Ultra-Reliable and Low Latency Communications (URLLC) devices) using these networks, network management and network slicing is evolving towards a service based architecture in which virtualization is used. To provide network management and slicing, a number of work items may be developed, including network provisioning and resource management, fault supervision, and performance management (PM) and reporting.

Network slicing is a form of virtualization that allows multiple virtual networks to run on top of a common shared physical network infrastructure. Network slicing serves service requirements by providing isolation between network resources, as well as permitting an optimized topology and specific configuration to be developed for each Network Slice Instance (NSI). The different parts of an NSI may be grouped as Network Slice Subnets that allow the lifecycle of a Network Slice Subnet Instance (NSSI) to be managed independently from the lifecycle of an NSI. The NSSIs may be implemented as different core networks, such RAN and 5GC.

Lifecycle management of an NSSI may include creation, activation, modification, de-activation and termination of the NSSI. Similar management occurs for NSIs. During creation, for example, resources are allocated and configured to satisfy the NSI or NSSI requirements. During operation, performance measurements generation, collection and reporting may be undertaken.

However, while legacy PM Integration Reference Points (IRPs) such as Basic core management (CM) IRP, Bulk CM IRP, Kernel CM IRP, are able to operate for the existing network management architecture, the existing network management architecture is not a service-based architecture. The network management architecture therefore may be unable to be used to provide PM for 5G networks and network slicing.

FIG. 4 illustrates measurement job control services in accordance with some embodiments. The services provided by each measurement job control service are shown, which may be performed by one or more of the devices shown in FIGS. 1-3. The producer may be for example, in an EM (managing the network functions), or within the controlled NF or a separate element connected with the controlled NF. As illustrated, the network measurement job control service producer consumes an NF measurement job control service to produce the network measurement job control service, the NSSI measurement job control service producer consumes an NF measurement job control service or another NSSI measurement job control service to produce the NSSI measurement job control service, and the NSI measurement job control service producer consumes an NF measurement job control service, and/or NSSI measurement job control service to produce the NSI measurement job control service. The original NSSI measurement job control service producer may send requests for performance measurement jobs to the other NSSI measurement job control service producer(s) and/or NF measurement job control service producer(s), receive the responses about the measurement job creation(s). The original NSSI measurement job control service producer may collect the performance measurements from another NSSI measurement job control service producer(s) and/or NF measurement job control service producer(s), and aggregate the performance measurements (perhaps doing additional processing) to the performance measurements of the original NSSI, and then report performance measurements of the original NSSI to the customer. The NSSI measurement job control service producer may thus do more than merely aggregation of the performance measurements.

The performance measurement jobs produced by the various producers may indicate which performance measurements are to be collected, the period of collection and where the performance measurements are to be delivered, among others. The measurements requested may include network measurements such as packet transmission/reception or handover performance (e.g., number of requests and failures/successes) between neighbor cells. The results of the performance measurements may be used, for example to determine KPIs or for network optimization.

The following use cases describe the functions of performance measurement job creation for Network Function (NF), NSI, NSSI and network. The performance measurement job creation of the different use cases add that upon receiving the request, the service producer first checks whether the performance measurement jobs to be created for monitoring the NF/NSSLNS/network performance already exist and if the performance measurement job exists, the service producer sends a response indicating that the requested performance measurement job can be supported by the existing job; otherwise, a new performance measurement job is created. Similar changes may be added in the post condition to indicate that the requested performance measurement job is supported by the existing job or new job. The performance measurement job control service producer may further request another measurement job control service producer to create measurement job(s) for the constituent NSSI(s)/NF(s). The measurement job control service producer may collect the performance data from the performance data reporting service producer (e.g., performance data file reporting service producer, or performance data streaming service producer) for the NF(s) or constituent NSSI(s)/NF(s), aggregate or calculate (or process) the performance data per the measurement job creation request, and send the performance data report(s) to the consumer.

The network discussed herein may be a complete network or a sub-network.

Thus, the use cases in TS 28.550 may be provided as:
